Hood plastic grade 1 usually refers to a repair grade in automobile maintenance. When the engine hood is slightly collided or damaged, the repair shop will evaluate the engine hood and repair it according to the damage degree. The plastic grade 1 indicates that the engine hood is slightly damaged, and it can be repaired by some simple repair work without a lot of replacement or modification. Repair methods may include repairing the paint surface, directly repairing or replacing some parts on the hood, etc. It should be noted that the plastic grade 1 is only applicable to minor surface damage. If the damage is serious or the hood structure is damaged, it may be necessary to repair or replace the whole hood with another grade hood.
